There are many silane-terminated polymers available today – but only one original:
Kaneka MS Polymer!
With over 40 years of experience and more than 30 different polymer types – varying in molecular weight, degree of branching and silylation, and reactivity – Kaneka offers its customers a unique toolbox for formulating high-performance elastic adhesives, sealants, and coatings. Acrylic-modified grades extend this performance range, delivering benefits such as excellent adhesion to various substrates and further enhanced weather resistance.
A common feature of all MS polymers is that they crosslink via atmospheric moisture. After curing, the final products exhibit a Shore A hardness between 15 and 85, with tensile strengths even exceeding 12 MPa.
MS Polymer in pure form is free from any hazard labeling. The end products’ formulations, i.e. compounded sealants or adhesives, are usually also free from such labeling requirements, depending on the selection of the other ingredients. MS Polymer-based products are well known for being free from isocyanates, solvents, and silicones. They keep an elastic behavior even at temperatures below zero degrees.
Possible uses?
The areas of application are diverse: the construction industry, the marine sector, general industrial applications, the automotive and transport industries, electric mobility, and much more.
Together with Kaneka, we provide our customers with technical service that covers every conceivable field of application – from high-performance solutions to cost-optimized formulations.

In addition to MS Polymer that is based on polyether chemistry, Kaneka offers the XMAP product group as another option for producing elastic sealants, adhesive sealants, and coatings. With these functionalized polyacrylates (X-Modified Acrylic Polymer), the “X” stands for different reactive groups that can be crosslinked by atmospheric moisture or free radicals.
The latter offers the possibility of UV curing, thereby opening up fields of application that remain inaccessible to MS Polymers. Compared to MS Polymers, XMAP types are distinguished in particular by the following properties:
The reactive groups are solely positioned telechelically – that is, located at the chain ends. This results in significant differences compared to conventional acrylate polymers, which exhibit a random distribution of these groups. Furthermore, the living radical polymerization method used for XMAP polymers yields a very narrow molecular weight distribution with homogeneous properties.
You want to use UV technology or elevated temperatures for curing? You are looking for products with exceptional oil resistance? Then XMAP is the obvious choice! XMAP is suitable for applications in sectors such as the automotive and construction industries (including as a sealant for self-cleaning glass), the electronics industry (including battery technology), and marine applications – as well as anywhere where temperatures exceed 100°C. It is also used in CIPG and FIPG applications on the market.

EPION is the trade name for a small group of reactive specialty polymers based on a polyisobutene backbone. As with MS Polymer and XMAP, a living polymerization technique is employed – in this case, living cationic polymerization.
End-group crosslinking of the polymer chains occurs either via platinum-catalyzed hydrosilylation of allyl groups or through radically crosslinking acryloyl groups. The formulated sealants are distinguished by outstanding barrier properties against gases and water vapor; furthermore, they enable the production of materials with exceptionally low hardness, even in the absence of solvents, oils, or plasticizers. They offer excellent weather stability.
EPION is used in applications where these properties are essential – for example, for seals inside fuel cells or within their cooling circuits, where the seals are exposed to water/glycol coolant mixtures. The end products are typically multi-component systems. EPION is a relatively high-priced polymer.
