Two-component polyurethane sealant includes A component and B component, and the two components react to cure. A component is milk white or light yellow viscous prepolymer of polyurethane. B component is black paste or liquid that is produced by curing agent and auxiliaries mixed and dehydrated. It has certain elasticity and cohesiveness after curing.
(A:B=10:0.8~1.2)
And it maintains good air tightness and water resistance in continuous stretching, vibration and Temp. changes, while oil resistance, solvent resistance,

Usage Method
ard: GB/T13477.1/2/3/5/6/8/10/11/13/17/19-2002
(ISO13640:1999, ISO 9048:1987, ISO 9047:1989, ISO 7390:1987, ISO 8339:1984, ISO 8340:1984 etc.)
Handle Tips:
It is required that the surface of the structure must be dry, clean and free of oil pollution.
Before construction, put protective tape on both sides of the crevice to prevent the leakage of paste dirty structures.
The white material (component A) is mixed with black material (component B). After fully stirring with a high-
power electric drill, the paste is filled into the crevice and compacted and scraped flat with a gray knife and other
tools.
Note:
- In order to ensure the technical requirements of products, samples should be made before construction. Forming quality ratio is white material (component A) and black material (component B) = 10:1 (JINGTONG manufacturer matched the proportion before package).
- The sealant should be used up as soon as possible to avoid waste caused by slow solidification of paste.
- Avoid flooding and rain within 24 hours after completion of construction.
About Carton Box Package Component:
- Weight of 25 kg / box, built-in 6 white plastic bucket, five white bucket polyurethane sealant called A component, by weight of about 4.54 kilograms per barrel.
- Also known as a bucket of black hardener component B, is divided into five plastic packaging bags, each bag weighs about 0.46 kg.
- That group of five parts per box, the weight of each A + B component is 5 kg.
- A component is milky white or light yellow sticky polyurethane prepolymer. B component is black paste or liquid formed by mixing and dehydrating curing agent and additives.
