Sarnacol®-2152
Two-component solvent-free polyurethane adhesive for Sarnafil membranes
Product Overview
Sarnacol-2152 is a two-component, solvent-free polyurethane adhesive for bonding Sarnafil roof membranes to the substrate without heat or open flame. Comprising a filled polyol component and an isocyanate hardener, it cures to a tough bond and is applied cold, which simplifies safety on site. Its thixotropic consistency makes it controllable during placement, and it can often be used without a primer while still preventing lateral water migration between the structure and the membrane. It is used to bond Sarnafil G 476 (unexposed) and Sarnafil G 410 L Felt (exposed) membranes to concrete, cement mortar, plywood, timber boards and cross-laminated timber (CLT) panels. Space Arc Engineering, an authorized Sika distributor in India, supplies Sarnacol-2152 for adhered single-ply roofing systems.
Features & Benefits
- Solvent-free, cold-applied bonding with no heat or open flame needed on the roof
- Thixotropic consistency gives good control during application
- Often usable without a separate primer, streamlining the build-up
- Helps prevent lateral water migration between the deck and the membrane
- Suitable for modern substrates including plywood, timber and CLT panels
- Pre-proportioned two-component set for consistent mixed performance
Technical Highlights
| Coverage | Consumption is approximately 500 to 1,000 g/m depending on substrate roughness and absorbency. |
| Strength | Substrate guidance includes minimum concrete compressive strength of 25 N/mm and pull-off strength of 1.5 N/mm. |
| Performance | Two-component PU adhesive; pot life about 30 minutes at +20 C, shortening to around 15 minutes at +30 C. |
| Application Conditions | Apply between +5 C and +40 C; mixing ratio A:B is 100:19 by weight, mixed to a uniform white colour. |
| Packaging | Supplied as a 30 kg set: 25 kg Component A pail plus 5 kg Component B pail. |
Applications
- Cold, flame-free bonding of Sarnafil membranes over concrete decks on commercial roofs
- Adhered roofing on cross-laminated timber (CLT) decks in modern timber buildings
- Membrane bonding over plywood and timber-board roofs on residential projects
- Roof waterproofing on cement-mortar screeds in industrial and warehouse buildings
- Adhered single-ply systems where hot works are restricted on infrastructure sites

Frequently Asked Questions
Is Sarnacol-2152 applied with heat?
No. It is a cold-applied, solvent-free two-component PU adhesive, so it bonds Sarnafil membranes without flames or hot works, which is helpful on sites where open flame is restricted.
Which membranes and substrates suit Sarnacol-2152?
It bonds Sarnafil G 476 (unexposed) and Sarnafil G 410 L Felt (exposed) membranes to concrete, cement mortar, plywood, timber boards and CLT panels.
What is the mixing ratio and pot life?
The two components are mixed at 100:19 by weight to a uniform white colour. Pot life is about 30 minutes at +20 C, dropping to around 15 minutes at +30 C, so mix only what can be used in time.
How much Sarnacol-2152 do I need?
Consumption is roughly 500 to 1,000 g/m depending on how rough and absorbent the substrate is. Higher rates apply to coarser decks, refer to TDS.
