THIOCURE®

THIOCURE® Polythiols for your benefitBased on our feedstock of mercapto carboxylic acids we have

introduced a series of polythiol products as reactive agents

in coatings, adhesives and sealants under the trade name

THIOCURE. Our THIOCURE product series represents a group

of solvent free multifunctional mercapto compounds with a

wide variety of viscosities and reactivities. Depending on the

nature of the THIOCURE compound the mechanical prop-

erties of the final product can be adjusted. In addition the

high sulfur content leads to coatings and adhesives with high

refractive indices.

Our THIOCURE products can be used in combination with

conventional epoxy, isocyanate and unsaturated systems.

They also show good performance as chain-transfer agents

(CTAs) in radical polymerizations.

THIOCURE® Customer Support Our Technical Service Center supports you in the development

of new formulations for use in coatings, adhesives, sealants or

optical applications. Thanks to many years of experience in these

fields we can quickly provide solutions to our customer’s pro-

blems and answer technical questions related to our products.

Benefit from our expertise and state-of-the-art technical and

laboratory equipment by contacting us with your questions!

THIOCURE® Customized Products In addition to our standard portfolio of THIOCURE polythiols

we manufacture tailor-made products for your application

from lab to industrial scale.

We are open for your ideas!

THIOCURE® Polythiols – highly reactive – solvent free – low viscosity – colorless

Epoxy Systems

THIOCURE Polythiols serve as curing agents for epoxy

resins in solvent free coatings, sealing compounds,

floor coatings and repair composites for the construc-

tion sector. The addition of THIOCURE allows formu-

lation of low temperature curing systems with lower

yellowing tendencies and adjustable flexibilities.

Thiol-ene Systems

In combination with unsaturated hydrocarbons

THIOCURE Polythiols react via UV or thermal initiated

radical addition („thiol-ene reaction“) showing high

reaction rates with double bonds. Thiol-ene systems

show lower shrinkage and no oxygen inhibition in

combination with adjustable flexibility compared to

standard unsaturated systems in coatings or adhesives.

Isocyanate Systems

THIOCURE Polythiols can be applied as main binder

or reactive thinner in combination with isocyanates

resulting in coatings, adhesives or castings with less

sensitivity against humidity in the drying phase and

improved UV resistance. The high refractive indices

of THIOCURE products enable fabrication of brilliant

surfaces and optical lenses.
