Siwin-M330
Silane Terminated Polyether Polymer
Description
Siwin-M330 is a type of polyether polymer that is terminated with alkoxy silane. It is ideal for use in moisture curing adhesive, coatings, and sealants. The sealants made with Siwin-M330 are known for their excellent adhesion properties and ability to bond to various substrates. Unlike polyurethane and silicone systems, this formulation does not contain solvents or isocyanates, which means there are no bubbles or odors produced during curing. It is particularly well-suited for use in the construction, transportation, and general industries.
Physical Data
Siwin Brand | Siwin-M330 |
Chemical Name | Silane Terminated Polyether Polymer |
CAS No. | 216597-12-5 |
Appearance | Transparent to slight yellow viscous liquid |
Boiling Point | ＞250℃ |
Flash Point | ≥237℃ |
Viscosity | 32000-42000 mPa·s (25℃) |
Gravity | 1.0 g/cm3 |
Water-Soluble | Virtually Insoluble |
Shelf Life | ≥12 months （25℃/50% RH） |
Properties and Features
This product boasts several key features and properties, including a high level of activity and low-medium modulus. It also has good adhesion strength and tensile elasticity, and cures quickly. If necessary, non-tin catalysts can be used. Siwin-M330 is also resistant to aging, water, solvents, and yellowing, and has an excellent elastic recovery rate. It is solvent-free, odorless, and eco-friendly, making it a great choice for environmentally-conscious applications.
Applications
Siwin-M330 is commonly used as a base polymer in elastic sealants, elastic structure sealants, encapsulate adhesives, and coatings. Its moisture curing ability makes it suitable for use in both single component and two component systems. It is often used in the transportation industry as a sealant, as well as in medium and low modulus construction sealants. It can also be used as a transparent encapsulate adhesive or as a personal DIY seal.
Instructions
Siwin-M330 can be quickly dissolved in ordinary organic solvents (such as ethanol), but almost insoluble in water. So the raw materials in the formula system are mostly oil-soluble substances. Siwin-M330 curing mechanism, silane of both ends with the help of the catalyst react with water forming hydrolysis to generate Silanol, Silanol is crosslinked with catalyst to form a siloxane bond, resulting in a network-like structure. Although Siwin-M330 has a highly reactive group, it can remain stable in the air for a period of time in a catalyst-free environment. Water is a very important factor during the storage and processing. In order to stabilize the processing and storage, it must add a certain amount of chemical water removal agent. Siwin-V31 is generally used as a water scavenger.
Storage
If unopened and stored at 4℃-30℃ dry environment, the shelf life is 12 months. Use it as soon as possible if opened, the remain products should be resealed and stored at 4℃-30℃ dry environment.
But if shelf life expired, you can still use it only after you confirm the product is qualified.
Cleaning
This product can be removed before curing by the general solvent, such as ethanol, dimethyl carbonate. After curing can only be removed by mechanical means.
Package
◼ 50kg plastic drum lined with aluminum foil bag
◼ 200kg drum lined with aluminum foil bag
◼ 1000kg IBC
