Product Introduction

HGDT-9 is a catalyst for the production of polyurethane foams, polyurethane coatings, polyurethane rubbers, elastomers, and room-temperature curing silicone rubbers. It can promote the chemical reaction of isocyanate/hydroxyl group processed by further polyurethane, and is a highly active gel reaction catalyst.

Performance and characteristics:

It has high catalytic activity and easy to adjust. Small dosage , fast reactivity, highly effective. More environmentally friendly, healthy and safe. World-class advanced technology, directly produced from tin ingots into stannous octanoate products, no intermediate production links, higher stability. This helps to produce a betterquality foam with minimal metal residue.

Product Introduction

HGDT-25 is a metal tin catalyst that does not contain 2-ethylhexanoic acid (2-EHA), which is suitable for various types of polyurethane flexible foam formulations and molded polyurethane foams. It may beused in TDI or TDI/MDI polyurethane continuous machine foams, slabstock foams and molded foaming systems using water or CO₂ as blowing agents.

Performance and characteristics:

Excellent cross-linking catalysis, no 2-ethylhexanoic acid (2-EHA) solvent, zero solvent emission, the foam can pass the CertiPUR-US list of prohibited substances.

Product Introduction

HGDT-12 is a lauric acid organotin heat stabilizer and chemical agent with strong gel properties, which can be used in elastomers, adhesives, sealants, coatings, rigid foams, molded foams, RIM, etc. It can be used together with amine catalysts for high-speed production of high-density structural foams, spraying rigid foams, and rigid foam panels. The product is also a heat stabilizer, which is mainly used in the processing of PVC soft products, catalysts for silicone rubber, light and heat stabilizers for polyamides and phenolic resins, etc.

Performance and characteristics:

It is clear with good lubricity, and can be used in combination with other organotins. It is not easy to precipitate when used as a heat stabilizer in the processing of those soft products, and has a high synergistic effect when used in combination with metal soaps.

Product Introduction

HGDDT-9 can be used as a polyurethane catalyst, mainly in the production of flexible slabstock polyether polyurethane foams, and it can also be used as a catalyst for polyurethane coatings, elastomers, and room-temperature curing silicone rubbers. Since it is a bivalent tin compound, it remains in the PU foam after foaming and has no adverse effect on the foam properties.

Performance and characteristics:

HGDDT-9 uses food-grade additives as catalysts, and the content of stannous is higher, reaching more than 28%. Stronger oxidation resistance, high stability, and minimal metal residue. It has a lower odor, which can delay the decay of the product and extend the life of the product.
