YA-119 flame retardant silicone rubber products weathering characteristics: 1, flame-retardant performance, in case of fire no combustion, no self-extinguishing fire. 2, neutral cure for most construction materials without adverse reactions or corrosion. 3, has excellent adhesion with most building materials without a primer to achieve excellent bonding and sealing properties. 4, after curing, has excellent weather resistance, aging resistance, UV resistance, ozone resistance and high temperature performance. 5, has good flexibility and resistance to displacement deformation. Main purposes: 1, all kinds of fire doors and windows sealed bonding, sealing curtain wall engineering retardant layers. 2, various types of fire-retardant glazing seal. 3, fixed and flame retardant in electronics, electrical components seal. 4, various public spaces decorated fire, moisture seal. Instructions for use: 1, after the bonding material compatibility testing before use, make sure the product can meet the construction requirements and the substrate to be constructed, the proposed strip width (A) and thickness (B) ratio of A: B should be 2 : 1. 2, the construction of the contact surface with the sealant must be clean and dry. 3, cut the nozzle, and then glue gun to uniform pressure within the interface, glass, plastic and interfaces are good contact on both sides to ensure that the joints filled. Construction Summary: 1, can not be used as a structural adhesive assembly. 2, does not apply to all the leaking oil, plasticizers or solvents surface. 3, not for confined spaces or in direct contact with the surface of the food or drinking water. 4, the surface temperature of the substrate below 4 ℃ or above 40 ℃, not construction. 5, not an adhesive material containing copper or a copper alloy. Safety Tips: 1, sealants construction sites should pay special attention to maintain good ventilation. 2, such as the eyes accidentally come into contact with the uncured adhesive, should be promptly wash with plenty of water and consult a doctor. 3, the user before using this product, you must be compatibility and adhesion tests confirmed that the product can meet the construction requirements and the substrate. 4, the company only to give the product meets the quality assurance requirements, as the loss of the product during use due to any accident or improper use shall not be liable. Shelf life: Store in a dry environment and below 27 ℃ storage, storage period of 9 months. Compliance with national standards: B GF 20HM GB / T 14683-2003 GB/T2408-1996
