Polyurethane Catalyst CUCAT GF01/GF02 is developed to substitute for DBTDL (T-12) in the field of polyurethane CASE (Coating, Adhesive, Sealant and Elastomer) field. The representative application is the electronic potting adhesive products with MDI + castor oil system.
Typical Properties：
Product Model | Appearance | Chroma (Fe-Co) | Density (g/cm3,25℃) | Viscosity (mPa.s, 25℃) | Others |
CUCAT-GF01 | Yellowish Transparent Liquid | ≤ 5 | 0.988 | 255±50 | With light compound smell, soluble in normal polyurethane raw materials. |
CUCAT-GF02 | ≤ 4 | 0.981 | 183±50 |
Applications：
It is applicable to the formulation system of castor oil or modified castor oil and grease polyols. It is used for electronic potting adhesive, floor coating and other products.
Features & Advantage:
v Long pot life. There is less heating during the mixing operation. The mixing material is with low viscosity and good flowability. The pot life is more than 1/4 longer than that of T-12, which is more conducive to defoaming and filling micro gaps.
v Fast post curing. The post curing speed of CUCAT-GF01/GF02 is faster than that of T-12, which can effectively shorten the drying time and formation time.
v The catalytic selectivity is obvious. Compared with T-12, CUCAT-GF01/GF02 reduces the catalytic reaction of NCO and water, and is conducive to reducing bubbles, pinholes and other phenomena.
v CUCAT-GF02 is an upgraded version of GF01, which further prolongs the early mixture flow time and shortens the later curing time.
v It does not contain dibutyltin and has a wide range of application of environmental protection.
User’s Guide:
Ø When in use, it is recommended to add it into polyol (material P), add it below 80 ℃ after vacuum dehydration and defoaming, and stir evenly. It is not recommended to add it into the components of ISO ( material I). There is possibility of gel risk. If it need to add it into isocyanate component, the applicability test must be applied first.
Ø The dosage is related to the formula. The general dosage is 0.05 ~ 0.5% of the weight of P material.
Ø After normal use, the tank mouth must be closed immediately to avoid open placement.
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 shelf life, please do test to make sure the catalytic properties before use.
