Recommendations
• Selection of the product and the end of plastic; activation agent ancillary products to treat sticky substrate adhesion test must first be carried out prior to bonding; to ensure
They have good compatibility, while before use to ensure that the main glue, end of plastic, activators belong to the shelf life of qualified products.
• construction in strict accordance with the construction process, any action in violation of the construction process may cause bonding failure;
• This product is fully cured non-toxic; but before curing should avoid contact with the eyes; skin contact; if the eye; skin contact; first with
Soapy water or alcohol scrub, then rinse with water. If the situation is serious, they should immediately seek medical treatment.
