Products in Monomers & Intermediates: Chain Extender

Evonik Modifier 705 refers to SiH-terminated polydimethyl siloxanes utilized as plasticizers in addition-curing silicones. Due to their difunctional structure, these products do not crosslink but extend the chains of vinyl-terminated silicone polymers (Polymer VS). The use of these modifiers reduces crosslinking density and, consequently, the elastomer's hardness.

VERSALINK® 130 M is an aliphatic diamine chain extender used in the production of color- or UV-stable polyurea and polyurethane-polyurea hybrid systems. It is particularly beneficial for aliphatic systems that require color or UV-light stability. This chain extender effectively enhances the strength and hardness of the final elastomer or coating.

Aminopropyldiethanolamine (APDEA) is a liquid with a color ranging from pale pink to light brown. It serves as a chain extender or co-curing agent in a range of coating applications and functions as a reactive intermediate for various purposes, including paints and coatings, polymerization, and textiles.

Evonik Modifier 715 is another SiH-terminated polydimethyl siloxane plasticizer for addition-curing silicones. These products do not crosslink but extend the chains of vinyl-terminated silicone polymers (Polymer VS). The use of these modifiers is intended to decrease crosslinking density, resulting in softer elastomers.

DYTEK® A amine (2-methylpentamine-1,5-diamine) is a methyl branched diamine with differential reactivity of each amine group that allows for crystallinity disruption in various applications such as high temperature nylon and polyamides, polyurethane chain extenders, and epoxy hardeners. It is also used in applications such as water treatment, corrosion inhibition, and metalworking fluids where amine functionality and pH control are important. DYTEK®A has 93% recycle content.

GP® CL-7004 phenolic resin from Georgia-Pacific Chemicals is a thermoplastic novolac. It is used as a crosslinking resin for epoxy and polyester resins. Its low phenol content, convenient softening point, and melt viscosity are conducive for use in powder coatings.

GP® CL-7002 phenolic resin from Georgia-Pacific Chemicals is a thermoplastic novolac. It is used as a crosslinking resin for epoxy and polyester resins. Its low phenol content, convenient softening point, and melt viscosity are conducive for use in powder coatings.

DYTEK® DCH-99 (1,2-diamainecyclohexane) is a cyclic aliphatic diamine made of 100% reclaimed material that is used primarily in epoxy coatings and composites. It provides chemical resistance over a broad range of chemicals, which makes it a superior choice for industrial and marine coatings. Other applications include mining, oil & gas, and pharmaceutical intermediates.

K-FLEX® 171-90 is a chain extended version of K-FLEX® 188 with low crosslinker demand. Although it is slower reacting in isocyanate crosslinked systems than K-FLEX® 188, it offers improved adhesion and flexibility.

GP® CL-7003 phenolic resin from Georgia-Pacific Chemicals is a thermoplastic novolac. It is used as a crosslinking resin for epoxy and polyester resins. Its low phenol content, convenient softening point, and melt viscosity are conducive for use in powder coatings.
