Pumalastic^® MS

Technical Caracteristics

MS Polymer-based filler.

Advantages and Uses

• Interior and exterior use.
• Sealing joints and/or cracks.
• Sealing prefabricated concrete elements.
• Sealing joints in walls, ceilings and expansion joints between construction elements.
• Sealing joints in floors (Please check with our technical department for heavy load traffic).
• Securing multiple elements in the building: skirting boards (baseboards) and profiles.
• Excellent adhesion, between construction materials made of concrete, wood, brick, stone, aluminium, galvanized steel, copper, glass, PVC, except PP, PE and PTFE plastics; even on wet surfaces.
• Can be applied on joints with movement of up to ± 20% of their width. 
• Medium elasticity modulus.
• Curing even in the presence of water.
• Excellent resistance to UV exposure (does not crack or yellow).
• Good extrudability, easy to work with even in cold environments.
• Permanently elastic after curing, including at low temperatures.
• Does not form bubbles during the curing process (does not release CO2).
• Can be painted with water-based paints.
• Chemical resistance: Resistant to fresh and salt water, aliphatic solvents, mineral oils, grease, diluted inorganic acids and alkalis.
• Poor resistance to aromatic solvents, concentrated acids and chlorinated hydrocarbons.
• Does not need a hazard label.

Suitable Substrates

• The substrate should be sound, clean and free of dust, oil, grease, paint, residues of mold release agents, rust, old fillers and any protective covering which could interfere with the adhesion.
• It is not advisable to put this product in contact with asphalt or bitumen.
• Users must check the compatibility of the sealant with the substrate with respect to adhesion, chemical compatibility and producing stains.

Application Procedure

• A backer rod made of material that will not adhere to the filler should be installed beforehand in the joint in order to control the depth to be filled and ensure that the joint will work with just two faces (both sides of the joint).
• The backer rod should not have any susceptible notches that may cause bubbling of the joint.
• In the case of very shallow joints apply adhesive tape and avoid adhesion on three faces.
• Protect the edges of the joint with an adhesive tape for a better finish.
• Apply the cartridges with a universal manual applicator gun and screwing the plastic nozzle. Apply in such a way as to avoid air entrapment, keeping the depth and angle of the applicator gun constant.
• For narrow joints, apply the filler in a single step, and for very wide joints apply in three steps, the first two on the edges of the joint and the third on the bottom of the joint.
• Smooth the filler with a spatula that has been wetted in soap and water, pressing the filler appropriately against the edges and bottom of the joint. Remove the adhesive tapes and scrape the polymerized filler. Do not use solvents. 
• It is recommended that the joint is not filled at its most contracted or most expanded point but when it is at its mid-point.
• The filler can be painted when it has completely polymerized. Ideally use water-based paints and also consider the elasticity of the paint since is usually lower than the filler one. It is recommended that preliminary compatibility tests are carried out.

Recommendations

• It should not be applied on joints with movements greater than 20%.
• Do not apply at temperatures below +5ºC or above +30ºC.
• Consult the Technical Department for any application not specified in this Technical Datasheet.
• If it comes into contact with eyes, wash immediately with water and consult a doctor.
• For further information regarding the safe handling, transport, storage and use of the product, check latest version of the Product Safety Datasheet.

The information and instructions in this datasheet are based on our current tests and technical knowledge. They are intended as general guidance and do not constitute a binding commitment by PIDILITEPUMA MEA CHEMICALS LLC. It is the sole responsibility of the user to verify, prior to use, that the product is suitable for the intended application and to ensure that it is applied correctly and in accordance with applicable regulations and good industry practice.

PIDILITEPUMA MEA CHEMICALS LLC cannot control how its products are applied on site throughout the entire project and therefore cannot accept responsibility for their application by contractors or other parties involved in the execution of the work. Support visits to the jobsite by our technical staff do not change that. Our responsibility is limited exclusively to defects that can be directly attributed to the supplied products, whether used individually or as part of a system, caused by manufacturing defects.

It is the responsibility of the project designer, site manager, contractor, or other relevant professionals to ensure that the selected products are appropriate for the specific project, taking into account their properties, the substrate, site conditions, and any existing issues.

In the event of a claim, the original packaging must be provided to ensure proper product traceability.

Any performance values stated for PIDILITEPUMA MEA CHEMICALS LLC products or construction solutions, whether in UNE standards or other applicable standards, are based solely on the specific test conditions defined in those standards (such as substrate type, temperature, and humidity). These values may not apply to situations where products are tested or used under different conditions.
