Additives
RaynGuard Quick Dry is the new standard in sealcoat accelerators. This product is a specially blended additive formulated to significantly accelerate drying times for asphalt emulsion based asphalt sealers. RaynGuard Quick Dry contains advanced polymers and reactive features that are designed to free the water molecules from the sealcoat to the surface to assist in evaporation.
Manufacturing premium materials is our business. Our premium materials can be found on parking lots, roadways and airfields in many countries around the world.
Sealcoating in early spring, late fall or at night are a challenge. Set yourself up for success with RaynGuard Quick Dry. Potentially halve your evaporation in favorable conditions.
Not a one-trick-pony! RaynGuard Quick Dry also improves adhesion, promotes tenacity and longevity. Benefit from the potent ingredients in this copolymer.
Anywhere from 1 – 3% by volume. The more you use the better your results will be. You should run your own trials and record the weather conditions and the drying success at various levels.

All drying is driven by the atmospheric absorption of the water molecules released from sealcoat. If we think of the atmosphere as the engine that drives the drying and curing process, we can more easily understand how factors like temperature, wind and humidity affect the process. It is important to keep these in mind when planning work.
Warm air holds more moisture than cooler air. A volume of air at 90°F will absorb much more moisture than the same volume at 70°F. As a result, water is absorbed by the atmosphere at ever increasing rates as temperatures increase. The reverse is also true. As temperatures lower, less moisture can be absorbed.
A light breeze or even wind exposes the pavement surface to a greater volume of air. More air exposure increases evaporation rates. If the pavement is exposed to twice the amount of air in a given time, then the water absorption potential may also double.
There is a correlation between relative humidity and the atmospheric capacity of holding additional water vapor. Any increase in humidity reduces the rate of evaporation at the coating’s surface. This is especially true in climates which have cooler air but high relative humidity.
Warmer air has the capacity to hold more water and allows material to dry more quickly while cooler air loses drying capacity until eventually it can hold no more water.
Direct sunlight warms the pavement, the sealcoat, and the air close to the surface. This all helps evaporation. Direct sunlight also warms the general atmosphere and increases its ability to absorb moisture.
As air cools, such as at the end of day or evening, it can hold less and less moisture, and the rate at which it can absorb moisture also decreases. If the air cools enough, it may reach a “dew point” of 100%, which is the air’s maximum capacity to hold water.
On reaching the dew point, water absorption will stop, and, with any further temperature decrease, water may come out of the air and be placed onto any nearby surface, including your sealcoat. Your consideration of weather conditions should include a period of 24 hours forward from the time of application.
