Furan Acid Cured No Bake

KALTHARZ 70 P
Furan resin with minimum 70% Furfural Alcohol content. Kaltharz 70 P is a cold curing resin with low formaldehyde content and has very high productivity. Kaltharz 70 P has nitrogen content upto 1% maximum. It can be used for making moulds and cores for steel and gray iron castings. Most suitable for use in continuous mixers.

GHAFUR 909
GHAFUR 909 is a clear, thin urea-furan binder remarkable for its especially low odour level during processing for cores and moulds for gray cast iron, ductile iron, and non - ferrous light and heavy metals.

KALTHARZ U 185 / KALTHARZ 70 P
Furan formaldehyde resin contains very high FA content (85% min). Kaltharz U 185 is a cold curing resin with minimum Nitrogen and has very high productivity. It can be used for making moulds & cores for steel & gray iron castings. Most suitable for use in continuous mixers.

Activator 100T3
This is a common Hardener for all types of Furan Resins. This is a solution of organic acid from Sulphonic acid group and suitable to accelerate curing of Furan Resins even under low temperature conditions. Depending on customer requirements we have various grades like slow, medium and fast grade. Activator 100T3 gives excellent through curing due to mixture of organic acids.

THERMOSET U 6040
Furan hot box resin used for non ferrous casting. It has excellent collapsibility at temperature below 1000˚C. Thermoset U 6040 has longer bench life when mixed with hardner 6040. In Furan hot box resin, curing takes place at 180˚C only. Thermoset U 6040 produces very low gases at pouring temperature.

HARDNER U 6040
Hardner 6040 is a curing agent for the Furan hotbox thermoset process. The low acidity of the catalyst insures a long bench life for the mixture, with rapid curing in the hot core box or in the drying oven.

Phenolic Ester Cured

SINOTHERM 5022
Sinotherm 5022 is an alkaline phenolic resole resin cured by esters. It has a very low odour level and it gives excellent flowability in sand mix. Sinotherm 5022 gives excellent collapsible properties after pouring. It can be used with all types of sands. It has very low nitrogen (less than 0.5%) and zero sulphur level. Depending on application requirement we have three major grades of Sinotherm 5022

SINOTHERM 5022 (A)
This grade is used for all type of casting wall thickness. Also most suitable on fresh sand.

SINOTHERM 5022 (B)
This grade is used for casting wall thickness less than 100mm. This is also called as hybrid grade due to resin composition.

SINOTHERM 5022 (A)
This grade is designed specially to avoid hot tear problem in casting.

ACTIVATOR 3340
Activator 3340 is based on combination of esters for curing sinotherm 5022, depending on customers requirement & criticality of casting. We have various grades of Activator 3340 as fast, medium and slow with bench life from 3 minutes to 40 minutes.

Phenolic Urethane Amine Cured

GASHARZ 5271
Gasharz 5271 is a benzylic ester type synthetic resin for cold box process. It is remarkable for its high thermal stability and long bench life of the sand mixture, low odour levels. It is characterized by very low sticking tendency and low moisture sensitivity. This is a three-part system with Activator and liquid amine catalysts which cures the resin.

CATALYST 5271
Catalyst 5271 is tertiary amine initiator for the cold box process.

Activator 4108
Activator 4108 is isocynate base hardner. It is used in combination with Gasherz 5271 for making Cores.

Gasherz 6348
Polyurethane cold box resin with high thermal stability at high temperature. Gasherz 6348 provides excellent releasing properties which improves productivity. this resin also provides excellent moisture resistance. This has VOC compounds due to aliphatic ester used in solved system. Due to higher curing speed, this resin improves productivity.

Activator 5333
Activator 5333 is used with Gasharz 6348 for making cores. It is based on isocyanate and combination of solvents for better properties while making cures. This also provides longer bench life properties when used with Gasharz 6348.

SHELL RESINS / NOVOLAC

RESITAL 4920 P
Resital 4920 P, Phenolic Novolac Resin is in powdered form. Resital 4920 P can be tailored according to individual requirement of Flow length, Melting point, Curing time This phenol formaldehyde novolac resin has a fineness of � 200 mesh min and is suitable for application in various industries such as refractory, moulding powder, grinding wheel etc. Resital 4920 has very good carbonization properties due to which it is an excellent source of carbon as well as a binder in the production of shaped refractory resin.

RESITAL 4920
Resital 4920 is liquid Phenol Formaldehyde Resin for coating of sand for making cores by Shell process. This resin is suitable for warm coating process.

Resital-4920 hsld
This is an improved version of shell resin with high strength & low dilation properties, specially suitable for water jacket cores. This resin provides higher cold strength than normal resin.

RESITAL 5100
Resital 5100 is liquid Phenol Formaldehyde Resin for coating of sand for making cores and moulds by shell process. This resin is suitable for warm coating process. Resital 5100 provides higher cold strength.

HARDNER R 4920 (Common for all shell Resins)
Hardner R 4920 is a White amorphous looking finely ground mixture of Hexa Methyl Tetramine and Calcium Streate in suitable proportion in order to impart ideal curing properties along with optimum releasing characteristics. When used as Hardner along with Resital 4920 (Phenol Formaldehyde Shell Resin). The ideal percentage to be used is 16-18% of Resital 4920 for a standard resin coated sand.

RESITAL 5100 / WJ
Resital 5100 / WJ gives high hot and cold strength. This resin also reduces cracking of cores in very low thickness cores specially water jacker.

RESITAL 5100 SSM
Faster curing shell resin with very high hot and cold tensile strength. Resital 5100 SSM, can be used for higher productivity and with low hardner addition (upto15-16 %) due to faster curing properties.

PHENOLIC HOT BOX

RESITAL 6861
Resital 6861 is a pure phenolic hot box resin modified with urea for use in warm and hot countries. The Nitrogen level is very low as a result the through cure is slightly slower than that of urea based phenolic hot box resin with higher nitrogen level. On the other hand there is the advantage that it is possible to work without using iron oxide. This resin is used in grey cast iron foundry and can be used on all types of core shooters.

Catalyst 6593
This is an aqueous solution of ammonium salts combined with a number of additives which ensure a long bench life. This is only reactive at elevated temperatures & initiates rapid cross linking.

Konserver
This is a bench life extender & composed of polymerized additives and aromatic solvents. This also improves the flowability and releasing properties of the Sand Mix.
