In addition to its excellent fire resistance, FV0 materials offer many safety, technical and economic advantages: Increase evacuation time: The thermal insulation maintains the fire zone at a stable level. This allows for longer escape…
Test method: Place the material sample vertically, expose it to the flame for 10 seconds, and after the combustion stops, the secondary combustion time does not exceed 10 seconds; and there is absolutely no molten…
Fire rating FV0, also known as UL 94 V0; is the highest level of protection in the UL 94 fire rating system published by Underwriters Laboratories. This standard assesses the ability of a material to…
Since silicone sealants have excellent sealing and bonding properties, they are widely used in the following scenarios: 1. Construction and decoration: • Door and window sealing: fill the gap between door and window frames and…
Glass glue (silicone sealant) is a sealing material widely used in construction, decoration, automobile, electronics and other fields, with excellent adhesion, weather resistance and chemical resistance I. Types of glass glue and key points for…
You must know these little-known facts about silicone sealant What is silicone glue? First understand its “identity label” Silicone glue, known as “all-purpose glue” in the industry, has polydimethylsiloxane as its core ingredient (sounds complicated?…
What are the reasons for slow curing of sealants? (1) Low temperature. The construction temperature of sealants should be kept at 10~40℃. If the temperature is too low, it is necessary to extend the curing…
What are the reasons for poor adhesion between the sealant and the substrate? 1) No adhesion test was performed before construction or the construction was not carried out according to the method recommended by the…
1. What should I do if a lot of bubbles appear when applying glue? In general, the causes and solutions of bubbles are as follows: (1) Cause: bubbles generated during glue injection; Solution: smooth glue…
Different Density of Sealant Density of adhesive is one of the important physical parameters. It represents the mass per unit volume of adhesive (usually measured in g/cm³ or kg/m³). Density not only affects the…
