YK - 670 PU putty, curing, high density of coating and close the gender is wonderful, excellent durability.Mainly used for wind turbine blades, etc.
FRP, steel plate, iron plate and old paint film, etc
Ratio of the construction
Atomic ash: curing agent = 6:1 2 (weight ratio)
Note: the operational time of 6-12 minutes (according to the proportion of curing agent and temperature changes in different)
The construction technology
Substrate processing: use P80 - P120 for blowing ash substrate surface of sand paper burnish, go to the oil and water, dry.
Mixed aside: will the Lord grey and form a complete set of curing agent by 6:1 2 mixed evenly, make the colour and lustre is consistent.
Coating: put the atomic ash in 6-12 minutes / 25 ℃ operational time, coating on the treated surface of the substrate.
3 hours after polishing, coating / 25 ℃, dry grinding.
Matters needing attention
1. The surface if there are air bubbles infiltration, must be thoroughly with scraper, leveling in order to ensure good adhesion.
2. PU putty with special curing agent, shall not be ash curing agent mixed with other atoms.
3. PU putty and hardener easy water curing, after open access should be kept sealed as soon as possible.Atomic ash with curing agent added back into the tank.
4. Store in a cool, dry place, away from heat and fire, avoid direct sunlight.
5. Storage time: 12 months / 25 ℃.
