fast drying, strong adhesion, waterproof, anti-mildew, acid, alkali and other characteristics
Artificial turf PU adhesive CF-918
CF-918 is our concentrated development of micro-foam-type two-component polyurethane adhesives, specialty adhesive backing for the use of various types of artificial turf, carpet and other industries which features by fast drying, strong adhesion, waterproof, anti_mildew, acid, alkali and other characteristics. Component A is the black active hydrogen , Component B is a crosslinking agent,two-component mixing ratio = 80:10 to 60:10, the optimal ratio of 70:10.
1. Simple construction, can also be heat cured or at room temperature curing;
2. Solvent-free, formaldehyde-free, no free TDI, without the use of any harmful substances volatile, green;
3. Fast curing, high bonding strength, waterproof, mildew, acid and alkali resistance, gasoline4. Excellent foaming-self characteristics,greatly improve pedaling comfort.
5. Adaptability to environmental conditions, equipment requirements low.
6. Low temperature activation of a long, hot and dry quickly.

Drying time (Mixing ratio 7:1)
1, when the material temperature is below 5 ℃, do not recommend the use of this product. If the material temperature is too low, it is recommended to place component A and component B at a temperature of 10-20 ℃ environment, then placed overnight. Temperature is too low, the component B crystals.
2, When the material temperature exceeds 20 ℃,and more than 30 ℃,after mixing,activation time reduces significantly.It's suggested to placecomponent A and B at a temperature of 10-20 ℃ environment,then placed overnight.
3, The best conditions for usage:
Material temperature :10-20 ℃, ambient temperature: -10-30 ℃.
4, CF-918 are two-component PU foam glue with the material component A and component B.Normal ratio of component A: component B = 5:1 - 9: 1, the best ratio of 7:1.
5, CF-918 comprehensive list of material drying performance
Component A: B
Totally drying time
The ratio for Component A: Component B ratio islarger or smaller, prolonged dry thoroughly, and place the appropriate extension of time under the best ratio, dry the fastest, the best performance.
6, Although the CF_918 with its foaming characteristics, in order to further improve the foaming ratio, reduces the amount of glue, it is recommended to glue the mixing head portion, with dry air, nitrogen or carbon dioxide gas, which are conducive to hair gel bulbs, reducing the amount of glue.
7, Amount of gluing: high tufting density (casual grass), the dosage is about 700--800g/m2; tufted low density (Sports Turf): amount of plastic used in about 600-700g/m2.
Material temperature environment to determine: the material temperature :10_20 ℃, ambient temperature: -10_30 ℃. If the ambient temperature is too high, a modest proposal to reduce the material temperature, in order to ensure the activation period.
Bake warming, according to the proposal, select the appropriate temperature bake, make sure the temperature is stable, determine the speed of gluing machine.
Adjusting the height of the blade, depending on the height of the blanket of suede, determine the appropriate blade height.
Weighing Cup: Cup weighing repeated three times and averaged to determine the proportion of component A and component B, the best ratio of component A and component B is 7:1.
Open return system to ensure that the temperature of the material pressure, smooth out the feeding amount.
Discharge, open machine, the normal construction, inspection, self_test, according to the dry conditions, pull-out strength, the foam case, you can always adjust.
After construction is completed, shut down the system as much as possible, open cleaning system, timely cleaning mixing head and blade system, cleaning carried out over at least twice to ensure a clean mixing head.
Storage requirements: The product should be stored in dry and ventilated warehouse, avoid direct sunlight, between -30 ℃ to 30 ℃ transport and storage, valid for one year.
