Thermal Conductivity (W/m·K) 0.022-0.024 0.026-0.028
Compressive Strength (MPa) 1.5-2.0 1.2-1.5
Shrinkage (%) <1% 2-3%

Flexible Foams

Flexible polyurethane foams are commonly used in seating, mattresses, and cushioning. These foams require a different set of properties compared to their rigid counterparts, such as elasticity and resilience. ZR-70 helps to improve the flexibility and durability of these foams by promoting better cross-linking between polymer chains. This results in foams that maintain their shape and performance over time, even under repeated compression.

Elongation at Break (%) 300-400 250-300
Tensile Strength (MPa) 1.8-2.2 1.5-1.8
Resilience (%) 60-70 50-60

Epoxy Systems

Epoxy resins are another area where ZR-70 excels. Epoxy systems are known for their excellent adhesion, chemical resistance, and mechanical strength, making them ideal for use in coatings, adhesives, and composites. However, the curing process for epoxies can be slow, especially at low temperatures. ZR-70 helps to speed up this process while maintaining the desired properties of the cured resin.

Coatings

Epoxy coatings are widely used in industries such as marine, automotive, and infrastructure due to their superior protection against corrosion and environmental factors. ZR-70 enhances the curing process of epoxy coatings, allowing for faster application and shorter downtime. Additionally, the low-odor profile of ZR-70 makes it suitable for indoor applications, such as flooring and wall coatings, where air quality is a concern.

Cure Time (hr) 2-4 6-8
Hardness (Shore D) 75-80 70-75
Adhesion (MPa) 5-6 4-5
Corrosion Resistance (hrs) >1000 800-1000

Adhesives

Epoxy adhesives are used in a variety of applications, from bonding metals and plastics to repairing damaged structures. The strength and durability of these adhesives depend on the completeness of the curing process. ZR-70 ensures that the epoxy adhesive cures evenly and thoroughly, resulting in stronger bonds that can withstand harsh conditions.

Lap Shear Strength (MPa) 20-25 15-20
Peel Strength (N/mm) 5-6 4-5
Impact Resistance (J) 50-60 40-50

Composites

Epoxy-based composites are used in aerospace, automotive, and sporting goods industries due to their lightweight and high-strength properties. ZR-70 helps to improve the mechanical properties of these composites by promoting better fiber-matrix adhesion and reducing void formation during the curing process. This results in composites that are stronger, lighter, and more durable.

Property With ZR-70 Without ZR-70
Tensile Strength (MPa) 120-140 100-120
Flexural Strength (MPa) 200-220 180-200
Impact Strength (kJ/m²) 100-120 80-100

Benefits of Using ZR-70

Reduced Defects

One of the most significant advantages of using ZR-70 is its ability to reduce defects in complex structures. Defects such as voids, cracks, and uneven curing can compromise the integrity and performance of the final product. ZR-70 addresses these issues by promoting uniform and complete curing, ensuring that every part of the structure receives the same level of attention.

Imagine a large composite aircraft wing. If the curing process is not uniform, certain areas may cure faster than others, leading to stress concentrations and potential failure points. ZR-70 ensures that the entire wing cures at the same rate, reducing the risk of defects and improving the overall reliability of the structure.

Faster Curing Times

Time is money, and in manufacturing, every second counts. ZR-70 accelerates the curing process, allowing for faster production cycles and reduced downtime. This is particularly beneficial in industries where time-sensitive deliveries are crucial, such as automotive and construction.

For example, in the production of automotive parts, faster curing times mean that more parts can be produced in a given day, increasing productivity and profitability. ZR-70’s ability to speed up the curing process without sacrificing quality makes it an invaluable tool for manufacturers looking to stay competitive.

Improved Mechanical Properties

ZR-70 not only speeds up the curing process but also enhances the mechanical properties of the final product. By promoting better cross-linking and fiber-matrix adhesion, ZR-70 helps to create materials that are stronger, more flexible, and more resistant to environmental factors.

Consider a high-performance bicycle frame made from carbon fiber-reinforced epoxy. The use of ZR-70 ensures that the epoxy matrix forms strong bonds with the carbon fibers, resulting in a frame that is both lightweight and incredibly strong. This combination of strength and weight reduction is essential for athletes who rely on their equipment to perform at the highest level.

Environmental Friendliness

In today’s world, environmental concerns are at the forefront of many industries. ZR-70 is designed to be environmentally friendly, with a low-odor profile and minimal volatile organic compound (VOC) emissions. This makes it an attractive option for manufacturers who are committed to reducing their environmental impact.

Moreover, ZR-70’s efficiency means that less material is needed to achieve the desired results, further reducing waste and resource consumption. In an industry where sustainability is becoming increasingly important, ZR-70 offers a solution that aligns with both economic and environmental goals.
