Low Modulus Silylated Polyurethane SPUR M3015
Manta SPUR M3015 is a plasticizer-free silylated polyurethane (SPUR) resin for one-component, moisture-curing sealants and adhesives. With low modulus and good elastic recovery, it is a base resin for joints in prefabricated concrete construction, road and building joint repair, high-transparency glass sealing and industrial joints with high movement requirements.
- Grade
- SPUR M3015
- Chemical Name
- Silylated polyurethane resin
- Form
- Slightly yellow viscous liquid
Overview
Manta SPUR M3015 is a silylated polyurethane resin for one-component, moisture-curing sealants and adhesives. It 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 and can be used as the base resin for low-modulus sealants and adhesives with high elastic-recovery requirements. Its silane groups react with atmospheric moisture, and curing is typically accelerated with organotin or amine catalysts; catalyst type and level should be determined in the specific formulation.
Manta SPUR M3050 is the medium-modulus counterpart for applications where tensile strength is required. SPUR M3015 is the low-modulus option for joints with high movement and elastic-recovery requirements, with a higher viscosity: 90,000 – 120,000 mPa·s at 25 °C compared with 35,000 – 55,000 mPa·s at 25 °C.

Applications
- Prefabricated construction: joints in prefabricated concrete (PC) construction
- Road repair: road joint and crack repair
- Building repair: building joint repair
- Glass sealing: high-transparency glass sealing
- Industrial joints: low-modulus sealants for joints with high movement requirements
Processing
The silane groups of Manta SPUR M3015 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
Why does it matter that SPUR M3015 contains no plasticizer?
SPUR M3015 is supplied plasticizer-free, so any plasticizer in the finished sealant is one the formulator chooses to add. The resin can be used as the base for low-modulus sealants and adhesives with high elastic-recovery requirements.
Where is SPUR M3015 typically used?
In low-modulus sealants and adhesives with high elastic-recovery requirements, for example joints in prefabricated concrete construction, road joint and crack repair, building joint repair, high-transparency glass sealing and industrial joints with high movement requirements.
How do SPUR M3015 and SPUR M3050 differ?
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 with high movement. SPUR M3050 is the medium-modulus grade (35,000 – 55,000 mPa·s at 25 °C) for applications where tensile strength is required.
