HM-WR49 silicone weather- resistant adhesive for construction is a kind of one-component, neutral curing, low modulus, high elasticity silicone rubber; it has good elasticity and displacement deformation ability, and has good adhesion to various powder coating metals The thixotropy of the product prevents it from sagging when it is applied in building joints, so it is especially suitable for the design of non- structural bonding, weather resistance, and waterproof sealing of various curtain walls; at the same time, it can be used in a wide range of climate temperatures It can be used, and it has good adhesion and compatibility to the surface of most substrates without primer. After curing, it is anti-aging, anti-ultraviolet radiation and extreme high and low temperature (-50- 150°C) changes; it has Low modulus performance, can bear the expansion and displacement capacity of the interface ± 25%, can be widely used in bonding and sealing.

Application

Application of glass curtain wall, aluminum-plastic panel curtain wall, door and window sealing and caulking
Non-structural adhesive assembly application of various curtain walls
Application of sealing and caulking between various metal and aluminum alloy doors, windows and walls
Glass, coated glass, tiles and masonry, concrete, etc.
Wood that does not seep oil

Usage Guidelines
It cannot be used for structural assembly
Do not use on surfaces where plasticizers or solvents may leak out, as this may cause damage to the sealant
It is not recommended to use it in a completely sealed space, which will cause it to not be able to cure completely due to lack of moisture
It is not recommended to use it in places that have been immersed in water for a long time
It is not recommended for structural surfaces that will come into direct contact with food
It is not recommended to use it on medical devices.

 
Construction
1. Cleaning of substrate surface

(1) The purpose of surface treatment before bonding is to remove oil, dust, surface damage and loose natural oxide film on the surface of the base material during the production and transportation process, so as to roughen the surface of the base material and form a surface suitable for mechanism embedding. morphology, while improving surface chemical properties and improving durability under the influence of stress environmental factors.

(2) Cleaning solvents are usually isopropyl alcohol, m ethyl ethyl ketone, and xylene. The cleaning cloth should be white, clean, soft, non-linting cotton.

(3) Use the "double cloth wiping" method to clean the surface of the substrate. Soak a clean cloth with solvent. Wipe the surface of the substrate in only one direction. Before the solvent evaporates, immediately use a second cloth with a clean dry surface. Wipe the solvent off the surface of the substrate.

(4) Do not put the soaking rag into the container for soaking, otherwise the clean solvent will be contaminated and the cleaning effect will be affected.

(5) Only clean the bonding and sealing construction part within 1 hour each time. Do not expose the cleaned substrate surface to the air for too long.

2. Make a bet
Use plastic tape to cover the surface near the interface to ensure that the sealing working lines are perfectly neat.
Cut the mouth of the hose, install the pointed tube, and then cut it at a 45° angle according to the size of the gap.
Install the sealant gun and press out the sealant along the gap at a 45° angle to ensure that the sealant is in close contact with the surface of the base material. When the joint width is greater than 15 mm, sealant needs to be applied multiple times. After gluing, trim the surface with a knife to remove excess sealant, then tear off the tape. If there are stains, use a damp cloth to remove them.

3. Pad material
Open-cell polyurethane or closed-cell polyethylene foam padding rods and polyethylene materials are recommended lining materials. Prevent sealant from sticking on three sides.
