Matters needing attention
When the sv-312 polyurethane windshield is applied in the immersion situation, it should be fully solidified before the flood.
It can be tinted, but it is recommended not to use solvent based materials such as colored enamel.
Do not allow wet coating technology, and recommend not to use solvents, water, detergents or soap solutions.
Before consulting Siway technicians, the use of high content chlorine disinfection areas such as swimming pools was not allowed.
Sv-312 polyurethane windshield wipers can be tinted with traditional methods, including epoxy resins and acrylic acid coatings, after full drying. Paint containing high solvent elements such as gloss enamel or high oil base paint will cause the surface reaction and soften the surface.
For optimum appearance and performance, the coating must be close to the tensile capacity of the js-311 polyurethane windshield. For the use of glue thickness less than 3mm, it can be colored after 24 hours. For the thickness greater than 3mm, it can be colored in 48 hours.
Health and safety
Sv-312 polyurethane windshield glass is a non-combustible product.
Prevent direct contact with the skin and eyes; If there is an accident, please contact the doctor.
If the skin touches, remove contaminated clothing and wash the skin thoroughly for 15 minutes or see a doctor.
The company in the technical support for customers to conduct a comprehensive
The construction of the
Cleaning the surface of A,
With gauze or other tools to remove the need for the dust on the surface of the coating parts, loose material, oil pollution and surface water.If you need to glue the parts have rust, first with a metal brush to clean, wipe the surface with acetone, alcohol.If you need to glue the parts with glue with blade or shovel knife tools such as clear the residue.
B, bottom coating agent, cleaning agent
In order to get the best adhesion performance, should use the corresponding bottom coating agent, cleaning agent.Besmear bottom coating agent, cleaning agent, it shall ensure uniform coating, bottomless accumulation of coating agent, cleaning agent or uncovered base material surface.
SV – 312 polyurethane windshield adhesive does not need to be mixed, direct use.
D, coating operation
With manual or pneumatic glue guns or other coating equipment to SV – 312 polyurethane windshield adhesive coating in the construction site, recommend best coating thickness 3.0 5.0 mm.
E, construction matters
Recommended products in temperature 15 to 35 ℃, humidity 50% – 75% RH construction under the condition of the best.When the environment temperature is low, the speed can not meet the technical requirements, the recommendations in the 50 to 60 ℃ oven 30 to 60 minutes.
