PIR Catalysts | VALIREX & VALIKAT K
Trimerization Catalysts for Rigid Foam - Polyisocyanurate (PIR) Insulation Systems
Our VALIKAT potassium catalysts are top-quality and high-purity potassium-based metal carboxylates designed to promote the trimerization of isocyanates in rigid polyurethane foam – PIR insulation systems.
By controlling the reaction profile and curing process, our trimerization catalysts ensure a highly cross-linked polyisocyanurate foam structure, providing the PIR foam with outstanding thermal insulation properties, as well as remarkable strength and durability.
Selecting the right catalyst is crucial for achieving the perfect rise and cure profile, leading to the desired end-properties of your PIR compound. Find the match for your optimal formulation in the overview below!
Potassium Octoate Catalysts
Potassium octoate, the go-to catalyst for PIR foam, delivers excellent trimerization performance. We offer various grades with different metal content and solvents, providing diverse benefits and characteristics. Explore our portfolio below.
| VALIREX K 10 DEG | Potassium octoate with 10% metal content, diluted in DEG. Low color. Trimerization catalyst for PIR foam. |
|
| VALIREX K 15 DEG | Potassium octoate with 15% metal content, diluted in DEG. Low color. Trimerization catalyst for PIR foam. |
|
| VALIREX K 15 DEG 30 | Potassium octoate with 14-15% metal content, diluted in DEG. Low-viscosity grade, low color. Trimerization catalyst for PIR foam. |
|
| VALIREX K 16 LO | Potassium octoate with 16% metal content, diluted in an OH-free solvent. Reduced isocyanate consumption. Trimerization catalyst for PIR foam. |
Potassium Octoate Replacement – Alternative Potassium Catalysts
We are actively developing alternative catalysts to replace traditional potassium octoate, addressing current toxicity concerns associated with the substance 2-ethylhexanoic acid and its metal salts.
