Pflaumer Brothers Introduce Next-Generation Aliphatic Isocyanate

New hardener for high-performance 2K waterborne polyurethane coatings.

Pflaumer Brothers announces the introduction of a next-generation aliphatic crosslinking agent developed for high-performance two-component (2K) waterborne polyurethane systems.

The new product, TERACURE® HP 47, is engineered to meet the performance demands of

industries such as automotive, aerospace, construction, flooring, wood finishing, OEM

production, and industrial coatings.

Based on Pflaumer test results, this advanced crosslinker delivers the long-term durability traditionally associated with solvent-borne isocyanates while offering the formulation flexibility and environmental advantages of waterborne systems.

TERACURE HP 47 is designed to provide the performance edge for a wide variety of

applications, including high-gloss wood coatings, chemical-resistant floor finishes on concrete, and tough exterior coatings for metal, composite, or plastic substrates

“TERACURE HP 47 is a water-dispersible aliphatic polyisocyanate hardener that combines

broad solvent compatibility with exceptional mechanical, chemical, and UV resistance,” says

Brian Morris, sales development and marketing director at Pflaumer. “The product enables the creation of durable, flexible, high-gloss coatings that can withstand abrasion, weather, and harsh chemical environments. TERACURE HP 47 delivers exceptional performance in

applications for heavy-duty floor coatings, clear topcoats, and high-traffic surfaces.”

According to Pflaumer, formulations based on TERACURE HP 47 with higher NCO:OH ratios, typically above 1.0, increase crosslink density and deliver higher hardness, improved chemical and solvent resistance, and enhanced toughness.

Pflaumer reports that coatings based on TERACURE HP 47 can be formulated with a variety

of additives to optimize properties and performance during and after application:

• Catalysts may be used to accelerate cure times in environments with variable

temperature and humidity.

• Wetting agents and dispersants improve pigment stabilization and overall gloss.

• Matting agents can be incorporated for satin or low-gloss finishes.

• UV stabilizers help extend the coating’s durability in outdoor conditions.

• Co-solvents can be used to fine-tune film clarity and cure profiles.
