Catalyst

WCAT-WS17

High catalytic activity at low temperature. It solves the problem that the curing of T12 is too slow at low temperature. It maintains good catalytic effect at low temperature (5 ℃), which shortens the curing time more than twice of that of T12. The catalytic activity is also higher than T-12 in summer. The storage stability is good, and the material viscosity is relatively low.

One-component Waterproof Coating

WCAT-WS13A

With high catalytic activity and fast drying speed, keep high activity at low temperature, solve the problem of slow curing in winter. The catalytic activity of WS13A is better than that of T12+DMDEE compound. It can give the material sufficient flow time, reduce bubbles and bulges, and have a long storage period.

WCAT-WQ01

Auxiliary drying agent. It can improve the stability of the latent curing system, improve the storage time, and protect the material. Improve storage time and the material is eco-friendly.

CUCAT-PD

Eco-friendly and highly active catalyst. It has the targeted characteristic of not catalyzing the reaction of trace water and isocyanate, avoiding the formation of CO2, avoiding the defects of tin (T-12) catalyst that is extremely prone to bubbling,bulging and peeling under high temperature and high humidity construction environment. The surface and body is dried at the same time, greatly improving the material performance, improving the aging resistance, and having a longer waterproof life.

Two-component Waterproof Coating

CUCAT-FS01

Eco-friendly and highly active catalyst, with the target characteristic of not catalyzing the reaction of trace water and isocyanate, to avoid the generation of CO2,  and the phenomenon of bubbling, bulging and peeling by using tin (T-12) catalyst under high temperature and humidity construction environment. Both outside and inside is cured simultaneously, which greatly improves the material performance, improves the aging resistance, and has a longer waterproof life.

AUCAT-F1/F2

For solvent-free waterproof coating. It can extend the flow time and shorten the curing time by using F1 and F2 together; Eco-friendly and not containing organic tin, reduce the toxicity to workers and the environment, and ensure to meet the stringent requirements of environmental protection regulations; The process is stable and the catalytic activity does not decay or fail during storage.

CUCAT-HA02

Polyurea Catalyst, effectively avoid bubbling and bulging, the colloid is dense and bubble-free and has higher strength. It has better reaction coordination than organic bismuth, Improve the synchronization of internal and external curing of thick coating. Reduce shrinkage stress caused by unsynchronized curing of thick coating.

Sprayed Polyurethane/Polyurea

BCAT-E16

General purpose organic bismuth catalyst, metal content 16%, no difference from the imported organic bismuth catalyst of the same type.

Crosslinker

(Chain

Extender)

TDMA-02

Liquid at normal room temperature and is easy to add, the equivalent is the same as MOCA, and the curing rate is fast.

Two-component Waterproof Coating

Anti-Catalyst

NCAT-YC02

It can effectively delay the reaction rate of polyurethane active groups, so that the material has a longer low viscosity operation time; It does not participate in the growth reaction of polymer chain segments and does not affect the physical properties of materials; Good compatibility, no phase separation; It does not contain restricted substances, and its environmental application is not restricted.

Viscosity Reducer

YRFC-11

Efficient viscosity reducing agent, with excellent powder dispersion and viscosity reducing effect, recommended for waterproof materials with high powder content, reducing viscosity, improving leveling, and not affecting material curing speed.

Anti-settling Dispersant

YRFC-12

Efficient anti settling and anti hardening agent. It can solve the problem of coarse particles and low mesh fillers being prone to settling and hardening at the bottom of the barrel. They have the characteristics of anti settling, leveling, and viscosity reduction, and are more inclined to improve the anti settling and leveling characteristics compared to dispersed viscosity reducers.

Liquid thixotropic Agent

YRFC-RG02A

Anti-sagging agent. It is used for one-component and two-component polyurethane waterproof coating. A small amount of addition can quickly form thixotropic non-Newtonian fluid. It is used for the construction of facades and ramps to prevent sagging.

Moisture

Scavenger

CUWR-WB50T

Milk white viscous liquid. Eliminate the influence of trace moisture in raw materials and reduce bubbles, bulges, hollows, pinholes and other phenomena.

Defoamer

YRXP-07A

High efficiency defoamer. It is generally used in non-aqueous solvent and solvent-free system, filler and filler free system. It has excellent foam inhibition effect,  and the dosage is low.

Waterborne Dispersant

YRFC-11W

Non ionic high-efficiency wetting dispersant, with a small amount added, can enhance the wetting effect of powder and substrate, effectively reduce the adsorption between powder particles, achieve wetting, leveling, dispersion and other surface effects, and avoid defects such as shrinkage pores and pits in the coating.

Applicable for water-based system

Waterborne Defoamer

YRXP-08W

A general-purposed and efficient defoamer for water-based systems, suitable for both filled and unfilled water-based systems. It has excellent foam inhibition and breaking effects with minimal addition and significant defoaming effects.
