Four Common Vinyl Flooring Adhesive Challenges—and How SAITACK® 970 Helps Solve Them

The vinyl flooring market continues to grow as luxury vinyl tile (LVT) and luxury vinyl plank (LVP) products become increasingly popular in commercial and residential applications. But for adhesive formulators, creating a flooring adhesive that delivers long-term performance is rarely simple.

Achieving the right balance of adhesion, durability, regulatory compliance, and moisture resistance can feel like an ongoing formulation challenge. Traditional polymer technologies often force formulators to compromise, leading to performance issues that can result in costly failures in the field.

Fortunately, advances in water-based acrylic technology are helping manufacturers overcome some of the industry’s most persistent obstacles. Below, we explore four common vinyl flooring adhesive challenges and how SAITACK® 970 can help address them.

1. Plasticizer Migration Resistance

One of the most significant challenges in vinyl flooring installations is plasticizer migration.

Vinyl flooring products contain plasticizers that provide flexibility and durability. Over time, these plasticizers can migrate from the flooring material into the adhesive layer. When this happens, the adhesive may soften, lose strength, or experience changes that lead to:

• Sticky residue
• Discoloration
• Flooring movement
• Reduced bond strength
• Premature adhesive failure

How SAITACK® 970 Helps

SAITACK® 970 is designed with excellent resistance to water and plasticizer migration. This helps maintain adhesive performance and long-term bond integrity, making it a strong building block for vinyl flooring adhesive formulations where durability is critical.

2. Meeting Low-VOC Requirements

Indoor air quality continues to be a major focus for architects, contractors, building owners, and consumers. Adhesives used during flooring installation can contribute to VOC emissions, particularly immediately after installation.

As sustainability standards and environmental regulations continue to evolve, manufacturers are increasingly seeking adhesive technologies that support low-emission flooring systems.

How SAITACK® 970 Helps

SAITACK® 970 is a true water-based adhesive technology with 0 g/L VOCs (EPA Method 24). This helps formulators create flooring adhesive systems that support low-emission requirements while maintaining the performance characteristics demanded by today’s vinyl flooring applications.

3. Solving the Tack vs. Shear Strength Dilemma

Adhesive performance often requires balancing two seemingly conflicting properties:

• High tack for efficient installation and immediate flooring placement
• High shear strength to prevent movement, creeping, lifting, or failure over time

Too much emphasis on one property can negatively impact the other, creating a formulation challenge that affects installation performance and long-term reliability.

How SAITACK® 970 Helps

SAITACK® 970 provides an excellent balance of tack and shear performance. This allows formulators to develop flooring adhesives that offer strong initial grab while maintaining the holding power needed to withstand long-term service conditions.

The result is greater confidence in both installation efficiency and long-term floor stability.

4. Moisture Stability in Real-World Conditions

Moisture remains one of the leading causes of flooring adhesive failures.

Whether it originates from concrete slabs, substrate conditions, or high-humidity job sites, excess moisture can negatively affect adhesive performance and contribute to:

• Bubbling and blistering
• Edge curl
• Adhesive breakdown
• Staining
• Mold-related issues beneath the flooring system

How SAITACK® 970 Helps

SAITACK® 970 offers strong water resistance, making it a valuable component in flooring adhesive formulations designed for moisture-prone environments. Improved moisture durability helps support longer-lasting flooring installations and reduces the risk of performance issues caused by challenging site conditions.

The Bottom Line

As vinyl flooring continues to gain market share, adhesive formulators face increasing pressure to deliver products that perform under demanding real-world conditions.

From plasticizer migration and low-VOC requirements to balancing tack and shear strength and improving moisture resistance, SAITACK® 970 offers a versatile solution to some of the industry’s most challenging formulation problems.

If you’re developing next-generation vinyl flooring adhesives, SAITACK® 970 can help provide the performance foundation needed to create durable, compliant, and reliable flooring systems that stand the test of time.
