Products in Printing & Packaging: Solventborne Sealant

WACKER® Crosslinker V 90 is a solvent-free hydrogenpolysiloxane containing reactive Si-H groups. It is known for its fast curing properties, good release stability, and excellent anchorage to a wide variety of substrates. The fast-curing properties of WACKER® Crosslinker V 90 also enable the use of a low platinum concentration.

SILRES® 64558 VP is a toluene-based, ready-to-use formulation based on polysiloxanes and silicone resins. The product is preferably used as a binder in highly flexible composite tapes or as an intermediate to manufacture silicone pressure-sensitive adhesive (PSA) formulations. In composite tapes, SILRES® 64558 VP contributes to the tapes' excellent electrical insulation properties and outstanding long-term heat resistance. Besides, composite tapes made with SILRES® 64558 VP are highly stable against environmental impacts such as moisture, pollutants, and UV light, allowing them to be exposed continuously to constantly changing climatic conditions or UV radiation.

CRA® 21 is an exceptional controlled release additive specifically formulated for adjusting the release force in solvent-based DEHESIVE® systems. As a solvent-based additive, it delivers high release levels, making it highly efficient in its intended application. Additionally, CRA® 21 exhibits good release stability, ensuring consistent performance over time.

CRA® 23 is a highly efficient controlled-release additive designed to adjust the release force in solvent-based DEHESIVE® systems. As a solvent-based controlled release agent, it provides exceptional release levels. Moreover, CRA® 23 exhibits good release stability, ensuring consistent performance over time. It also boasts an excellent bathing life.

DEHESIVE® PSA 11 AP is a solvent-free, reactive silane mixture. Applied with addition-crosslinking DEHESIVE® or DEHESIVE® PSA-systems, it increases the adhesion to the substrate. The rub-off resistance of the cured silicone coating is improved significantly. It provides improved anchorage to unprimed PET film.

FloraRez® 785 is a glycerol ester derived from highly hydrogenated gum rosin. This thermoplastic resin exhibits a very pale color and demonstrates remarkable resistance to oxidation and color degradation. It serves as a valuable tackifying resin component in diverse applications such as adhesives, inks, coatings, and personal care formulations, particularly in scenarios where oxidative stability is essential.

FloraRez® G85 is the glycerol ester of gum rosin, which is also known as ester gum. It is a pale-colored thermoplastic resin that has a low odor and low acid number. FloraRez® G85 is commonly used as a resin component in various adhesives, inks, coatings, and personal care compositions.

UNI-REZ 2210 polyamide resin is an alcohol soluble / co-solvent type resin with excellent solvent release and blocking properties. UNI-REZ 2210 polyamide resin was developed for release lacquers but can also be used as a modifying resin to improve hardness.

UNI-REZ 138 polyamide resin is an alcohol soluble type resin of comparatively low viscosity. It has low odor, high gel and water resistance, together with excellent solvent release and blocking resistance. Its high ester tolerance permits addition of small proportions of nitrocellulose without loss of any of these properties.

UNI-REZ 147 polyamide resin is an alcohol soluble / co-solvent type resin offering low temperature gel resistance and good compatibility with modifying resins. UNI-REZ 147 polyamide resin offers better blocking and gloss properties than other modified co-solvent types. It has good solvent compatibility, alcohol reducibility and compatibility to nitrocellulose.

The Micronized Products Mica 325# range of products are obtained as a co-product from the pegmatite ore at our mining operation situated in the Limpopo Province in South Africa. After separation the Mica is delaminated, screened, milled and classified to specific size specifications.

UNI-REZ 119 polyamide resin is an alcohol soluble / co-solvent type resin with excellent solvent release and blocking properties. UNI-REZ 119 polyamide resin was developed for release lacquers and has the lowest solution viscosity but fast solvent release.

UNI-REZ 110 polyamide resin is an alcohol soluble / co-solvent type resin with excellent solvent release and blocking properties. UNI-REZ 110 polyamide resin was developed for release lacquers but can also be used as a modifying resin to improve hardness.

UNI-REZ 2934 polyamide resin is a co-solvent type resin offering excellent low temperature gel resistance and good compatibility with modifying resins. UNI-REZ 2934 offers better blocking and gloss properties in comparison with other modified co-solvent types.
