EPO Joint Sealant

EPO Joint Sealant

Flexible, semi-rigid epoxy joint and crack sealer designed to protect concrete floors and joint edges.

EPO Joint Sealant is a 100% solids, non-shrinking, self-leveling epoxy compound designed for sealing control joints, construction joints, saw-cut joints and cracks in concrete floors.

Its combination of flexibility, strength and impact resistance helps protect concrete joint edges from chipping and deterioration caused by repeated traffic, including forklifts and other hard-wheeled equipment.

EPO Joint Sealant is supplied as a two-component 1:1 system and provides a durable, long-lasting seal for demanding industrial and commercial environments.

Where Is EPO Joint Sealant Used?

EPO Joint Sealant is well suited for:

• Control joints
• Construction joints
• Saw-cut joints
• Cracks in concrete floors
• Industrial manufacturing facilities
• Warehouses and distribution centers
• Processing and production areas
• Areas exposed to forklift and hard-wheeled traffic
• Repair and protection of damaged joint edges

Because the material is self-leveling, it flows into properly prepared joints and cracks to create a smooth, durable seal.

Flexible — But Not for Constantly Moving Expansion Joints

EPO Joint Sealant provides enough flexibility to accommodate the normal movement associated with many control joints, construction joints and concrete cracks.

However, EPO Joint Sealant is not recommended for expansion joints that experience constant, significant or extreme movement.

It is a semi-rigid epoxy joint sealant, not a substitute for a highly flexible elastomeric product specifically designed for expansion joints that continuously open and close.

If there is uncertainty about the amount of movement in a joint, contact Dynamis Epoxy before selecting the product.

Protects Concrete Joint Edges

One of the primary benefits of EPO Joint Sealant is its ability to support and protect concrete joint edges.

Repeated traffic across an unsupported joint can cause the edges of the concrete to chip, crack and deteriorate. This is especially common in facilities where forklifts, carts and other industrial equipment regularly cross floor joints.

EPO Joint Sealant helps support these joint edges while maintaining the flexibility required for many control-joint applications.

Chemical Resistance

EPO Joint Sealant provides resistance to many commonly encountered:

• Acids
• Alkalies
• Salts
• Petroleum products
• Oils and greases
• Detergents
• Food products
• Beverages
• Water

For applications involving a specific chemical, concentration or exposure condition, contact Dynamis Epoxy to confirm product suitability.

Standard and Low Temperature Cure

EPO Joint Sealant is available in both Standard Cure and LTC — Low Temperature Cure formulations.

Standard EPO Joint Sealant is intended for applications where concrete and joint temperatures are approximately 50°F or above.

EPO Joint Sealant LTC is designed for colder applications and may be used at temperatures as low as approximately 34°F.

Dynamis Epoxy uses 75°F as its standard room-temperature testing condition.

Temperature will affect both working and cure times. Warmer temperatures will accelerate the epoxy reaction, while colder temperatures will extend cure times.

Cure and Return to Service

At approximately 75°F, Standard EPO Joint Sealant typically reaches initial cure/tack-free condition in approximately 6–8 hours.

Foot traffic and rubber-tired traffic may resume once the material has reached the appropriate initial cure.

Allow approximately 24 hours before returning the area to steel-wheeled or hard-wheeled traffic.

At lower temperatures, cure and return-to-service times will increase.

Cure Terminology

At 75°F, both Standard EPO Joint Sealant and EPO Joint Sealant LTC have a pot life of approximately 1–2 hours, depending on material temperature, ambient conditions and batch size.

Initial Cure / Tack-Free
The surface is no longer tacky to the touch.

Ready for Service
The material can accommodate foot traffic and light-to-medium use or contact appropriate for the application.

Full Cure

Full cure: approximately 7 days.
The chemical reaction is complete and the product has reached its final hardness and performance properties. The product will not continue to become harder after full cure.
