Anti-hydrolysis Organotin Catalyst Equivalent to Fomrez UL-32, Niax* catalyst LC-5632

Typical Properties:

Solubility:Easily soluble in polyester and polyether polyol.

Features & Advantage:
AUCAT series catalysts are developed to solve the problem that common organometallic catalysts lose activity gradually in systems containing trace moisture, acid, alkali, etc, which cannot be stored stably for a long time. AUCAT-S032 is an anti-hydrolysis organic tin catalyst, with the following characteristics:
High catalytic activity. AUCAT-S032 is a strong gel catalyst with higher catalytic activity at low temperature than ordinary organotin DBTDL (T-12)
It strongly promotes gel reaction. When used in polyurethane foam together with amine catalyst, it can balance the gelling-foaming effect, promote the post curing of foam, and avoid adverse phenomena such as foam shrinkage and collapse.
Hydrolysis resistance and good storage stability. It can be premixed into the aqueous formulation system in advance. Compared with ordinary organotin, such as DBTDL (T-12), it has more durable hydrolysis resistance, solves the technical problem of hydrolysis failure of ordinary metal catalyst in aqueous formula, and makes the formula and process simpler, more stable and more flexible.

Applications:
It is widely used in all fields of polyurethane. CASE (coating, adhesive, sealant, elastomer). It is an excellent gel catalyst especially for polyurethane foam with stable and reliable performance. It is with wide applicability and better storage stability in polyol materials.

User’s Guide:
The general dosage is 0.03-0.3% of the weight of PU. For two-component polyurethane, the general addition amount is 0.05-0.5% of the weight of polyol components. For foaming system, it can be pre mixed into aqueous polyol components.
Normally, the packaging container must be kept sealed, and the can mouth should be sealed immediately after use.
Handling & Storage: Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain.

Package: 25kg/200kg in HDPE drum

Shelf Life: The unopened shelf life is 24 months from the date of manufacture. After expiration, it can still be used as qualified product if the catalytic activity does not attenuate.
