Medium Modulus Silylated Polyurethane SPUR M3050
Manta SPUR M3050 is a plasticizer-free silylated polyurethane (SPUR) resin for one-component, moisture-curing sealants and adhesives. It is a base resin for medium-modulus formulations where tensile strength is required, from door, window, kitchen and bathroom sealing in construction to seam sealing of buses and rail vehicles.
- Grade
- SPUR M3050
- Chemical Name
- Silylated polyurethane resin
- Form
- Slightly yellow viscous liquid
Overview
Manta SPUR M3050 is a silylated polyurethane resin for one-component, moisture-curing sealants and adhesives. It is a base resin for medium-modulus sealants and adhesives in industrial and transportation applications where tensile strength is required, and offers broad formulation latitude, strong adhesion to a variety of surfaces, good chemical and weathering resistance, good elastic recovery and long shelf life.
The resin contains no plasticizer. Its silane groups react with atmospheric moisture, so it should be stored and processed with moisture excluded. Curing is typically accelerated with organotin or amine catalysts; catalyst type and level should be determined in the specific formulation.
SPUR M3050 is the medium-modulus grade of the pair and the lower in viscosity: 35,000 – 55,000 mPa·s at 25 °C versus 90,000 – 120,000 mPa·s at 25 °C for Manta SPUR M3015, the low-modulus grade for joints with high elastic-recovery requirements.

Applications
- Doors and windows: perimeter sealing and waterproof sealing
- Kitchens and bathrooms: waterproof sealing; mildew resistance requires a suitable fungicide
- Floors and glass: floor joint sealing and high-transparency glass sealing
- Industrial sealing: seam sealing of buses and rail vehicles and weld-seam sealing of tricycles
Processing
The silane groups of Manta SPUR M3050 react with atmospheric moisture. Store and process the resin with moisture excluded; dry fillers before use and add a water scavenger such as vinyltrimethoxysilane (VTMO) to obtain adequate shelf life of the formulated product.
Curing is typically accelerated with organotin or amine catalysts; catalyst type and level should be determined in the specific formulation.

Frequently Asked Questions
SPUR M3050 vs SPUR M3015: which should I choose?
SPUR M3050 is the medium-modulus grade (35,000 – 55,000 mPa·s at 25 °C) for industrial and transportation sealants where tensile strength is required. SPUR M3015 is the low-modulus grade (90,000 – 120,000 mPa·s at 25 °C) for sealants with high elastic-recovery requirements, such as joints in prefabricated concrete construction.
What applications is SPUR M3050 used in?
In construction: door and window perimeter sealing and waterproof sealing, kitchen and bathroom waterproof sealing, floor joint sealing and high-transparency glass sealing. In industrial sealing: seam sealing of buses and rail vehicles and weld-seam sealing of tricycles. Mildew resistance in kitchens and bathrooms requires a suitable fungicide.
What resin-level advantages does SPUR M3050 offer formulators?
It is plasticizer-free, offers broad formulation latitude and strong adhesion to a variety of surfaces, and provides good chemical and weathering resistance, good elastic recovery and long shelf life in one-component, moisture-curing formulations.
Can I test SPUR M3050 before placing an order?
Yes. Samples are charged. The sample fee includes courier delivery and is deducted from your first formal order. Use Request a Sample and state the quantity and your application. The TDS is on this page; SDS and COA are available on request.
