All Acid Absorbers / Acceptors for Adhesives and Sealants

RA 150 by ICL is an active magnesium oxide. Possesses high purity and activity. Used in rubber and adhesives industries. Regulates the rate of vulcanization and prevents the development of "scorch" in the production of polychloroprene rubber. RA 150 acts as an acid acceptor and integral part of the bonding system in polychloroprene-phenol resin adhesives.

RA 40 by ICL is an active magnesium oxide. It possesses high purity and activity. It is used in rubber and adhesives industries. It regulates the rate of vulcanization and prevents the development of "scorch" in the production of polychloroprene rubber. RA 40 acts as an acid acceptor and integral part of the bonding system in polychloroprene-phenol resin adhesives.

Actmix® MgO-75GE F140 by Ningbo Actmix Rubber Chemicals is a magnesium oxide. Acts as a metallic oxide vulcanization activator, acid-acceptor, and adhesion promoter. Improves processing safety of CR, CSM, CM, CIIR, FPM, etc. and lowering the possibility of rubber compounds scorching by means of heightening the critical temperature of alkaline catalyst. It can lower the critical temperature of acid catalyst. Improves aging properties of halogen compounds especially CR and FPM. Actmix® MgO-75GE F140 can neutralize trace acid in cold vulcanization. It is compatible with NBR, SBR, AR and ECO. Its recommended addition level is 3-5 phr.

Akrochem® Zinc Oxide Transparent 9930 by Akrochem is an accelerator activator of extremely fine particle size. It acts as an acid acceptor in polychloroprene adhesives and used to achieve long open-tack times in the absence of magnesium- and regular zinc oxide grades. The latter two products reduce open time by reacting with terpene phenolic and phenolic resin, which are typical tackifiers for polychloroprene adhesives. It possesses very good dispersion characteristics in rubber compounds. Akrochem® Zinc Oxide Transparent 9930 raises compound viscosity and at a high level of addition, increases thermal conductivity and has a stiffening effect, improving the dimensional stability of extrusion and open cured goods. It does not cause a color change in vulcanizates and increase level enhances the mechanical properties of rubber goods, tear- and abrasion resistance.

Dytek® HMI (Hexamethyleneimine) by INVISTA is a clear, colorless liquid with an ammonia-like odor. Dytek® HMI (Hexamethyleneimine) is used in adhesives.

Rhenogran® MgO-75 by LANXESS is a curing activator and acid acceptor particularly for polychloroprene rubber (CR) and adhesives. It is a blend of magnesium oxide, polymer binder and dispersing agents. It is easy to incorporate and disperses quick and homogeneously in the mix. The dosage level of the grade is 2-4 phr. The storage stability of Rhenogran® MgO-75 is 365 days.

Non-reactive, non-hygroscopic, magnesium oxide. Used as a thickener and an acid acceptor in adhesives. Offers compatibility with neoprene, hypalon, natural rubber, SBR, viton, butyl rubber, chlorobutyl rubber and fluoroelastomers.
