Product Description
Modified silane sealant, referred to as MS sealant, is anti-pollution and environmentally friendly after curing. It is suitable for bonding and sealing the joints of various materials such as car bodies, train high-speed rail cars, elevator cars, containers, ships, and mechanical ventilation equipment. This product meets environmental protection requirements, does not contain harmful substances in GB18583 "Limits of Hazardous Substances in Adhesives for Interior Decoration Materials", meets the EU ROHS and REACH environmental protection standards, and meets the German environmental protection standards for automotive adhesives.
Scope of application
HY933MS sealant: used for sealing various welds and joints;
HY935MS sealant: higher shear strength, used for general material bonding and sealing;
HY936MS adhesive glue: high strength, used for bonding and sealing of various materials.
Product Features
1. Solvent-free, PVC-free, isocyanate-free, non-toxic, odorless, non-polluting, neutral and environmentally friendly.
2. The surface has good paintability and is compatible with most industrial paints. It can be sprayed after the surface is dry and does not affect the curing speed.
3. Excellent thixotropy and extrudability, wide applicable temperature range.
4. No primer is required, and it has excellent bonding properties to most metals such as aluminum, painted steel plates, glass, PVC, ABS, and polyester materials.
5. Excellent weather resistance, aging resistance, superior tensile and compression resilience.
Curing Mechanism
MS sealant is cured by hydrolysis and dealcoholization of silane and moisture in the air, and is a moisture-absorbing curing adhesive. Once the gel is unsealed, the gel absorbs moisture in the air and gradually solidifies from the surface of the gel to the deep layer to become an elastomer. The higher the temperature and the higher the humidity, the faster the curing; the curing speed would be slower in the low temperature and low humidity environment.
Resistant to Chemical Media
The product can be long time resistant to fresh water, sewage, wastewater, calcium carbonate aqueous solution, detergent, low acid, corrosive water solution, etc., and is short-term resistant to mineral oil, vegetable oil, fat, fuel, but not resistant to organic solvents, paint thinners, and high-concentration acids Alkali etc.
Instructions
1. The surface of the joint should be free of oil stains, dust, impurities, etc.
2. Cut the glue nozzle into the required size and shape according to the process requirements;
3. Cut off the sealant seal, install the glue nozzle, and put it into the glue gun;
4. Apply the sealant evenly on the joints, the thinnest part is greater than 1mm; when using the pneumatic gun, the air pressure is controlled at 0.3~0.5Mpa;
5. The product can be colored by traditional methods after surface drying, including epoxy resin and acrylic paint.
Matters Needing Attention
1. Avoid construction under 5℃ and humidity less than 20%.
2. Pneumatic pressure is strictly prohibited to exceed 0.5 Mpa, if it exceeds 0.5 Mpa, gas will enter the hard packaging tube, and colloidal bubbles will occur.
3. Because the coating contains high solvent content, the glue surface will become soft. In order to obtain the best appearance and performance, the glue should be colored after curing for 24 hours.
4. For special chemical reactions, please contact our technical department.
Packing Specification
Hard packaging: 310ml / tube, 50 tube / box
Flexible packaging: 600ml / strip, 20 strips / carton
Storage Method
MS sealant absorbs moisture and solidifies. It must be stored in a low temperature and dry environment. The shelf life of the soft pack is 6 months, and the shelf life of the hard pack is 3 months.
Safety and Healthy
Do not contact uncured sealant products with food and cosmetics;
The uncured sealant should not be in contact with the skin for a long time;
If the sealant accidentally gets into your eyes, you must immediately rinse with plenty of water, and then ask a doctor for examination;
Keep the product out of the reach of children.
